Introducing the IsoBox SERIES, with a NEW! product line (AN and CN models) of Medical Grade Isolation Transformers with low noise and low EMR (Electro-Magnetic Radiation). Four standard models are available in attractive aluminum cases for floor or wall mounting or for placement in the base of Hospital Medical Carts.

For Patient Care Areas*, our IsoBox Series offers added safety when using electronic or electro-medical devices. By connecting such apparatus to the IsoBox, you will benefit from the added protection and you may rest assured that you will be in full compliance with the legal requirements of maximum 100 µA leakage current and isolation as stipulated by the NEC (National Electrical Code) and UL (Underwriters, Laboratories) safety standard UL2601.1.

You can also realize some savings in your purchasing budget when buying standard commercial grade printers, video monitors, computers and other devices and connect them to our IsoBox, instead of paying for higher priced medical grade components. Our IsoBox will take care of the required maximum leakage current requirements for Patient Care Areas*.

There are two basic series available. The U.S. series operates at 117V/60Hz for U.S. and Canadian installations. The International series is designed to operate in North America as well as overseas and in South America.

Using our own design and manufacture of the toroidal power transformers for the IsoBox, we can achieve a voltage drop of only 6% for the 300VA rating and smaller for the larger power ratings. The toroidal transformer inside the IsoBox is virtually hum free, generates very low EMI (Electro Magnetic Interference) and runs quite cool, also at rated full load. Computer and video monitors can be sensitive to EMI as are many other electronic devices.

The Legacy A and C series have the output neutral wire grounded and are still available for purchase direct from the factory. These models limit the Ground Leakage Current when multiple equipment plug into the unit to comply with UL Ground Leakage Current limit. These models also allow plugging in regular UPS (uninterrupted power supply) to operate correctly. The A and C series are not for Chassis Leakage Current limiting. If your application requirement is to limit Chassis Leakage Current, we suggest that you use our new AN or CN series. The AN, CN, W and M series output neutral wire is not grounded. These models can effectively limit both Chassis Leakage Current and Ground Leakage Current.
